2FA: Transfer Authenticator to a New Device

Overview

If you're moving to a new phone, transfer your authentication method before wiping or giving away your old device. Keep both devices handy during setup. 

Available authentication methods include Microsoft Authenticator (preferred and most secure), Passkey, Security Key, and Hardware Token. 

Procedure

Add Authenticator on the New Device 

Set up your preferred sign-in method on your new device before removing the old one. 

Step 1

  1. From your new device go to https://mysignins.microsoft.com/security-info.
  2. Sign in with your myNMSU credentials.
  • An authentication request will be sent to your old phone to verify access.
  • Once approved, you'll be redirected back to the Security info page on your new device. 
  1. From the Security info screen, select Add sign-in method. 

  1. Choose Passkey, Security Key, or Hardware token.
  2. Follow the on-screen instructions to complete setup. 

Note: Phone-based authentication may be used only with prior approval and if no other option is available. Microsoft Authenticator is the recommended method. For step-by-step instructions on enabling 2FA, see the Microsoft Authenticator App Setup article.
